10 February 2010 COPUOS - Vienna 1 AGILE: an Italian Small Mission

AGILE: an Italian small scientific mission

• Devoted to high-energy astrophysics • Optimized for a low-cost/high efficiency of scientific performance • Launched on April 23, 2007 from India • Active in synergy with other satellites and observatories around the world • Very important scientific results • An observatory also for Terrestrial phenomena The AGILE Payload: the compact instrument for high- energy astrophysics

It combines for the first time - a -ray imager (30 MeV- 30 GeV) with a - hard X-ray imager (18-60 keV) with large FOVs (1-2.5 sr) and optimal angular resolution AGILE: 2 and 1/2 years in orbit…

• ~ 14.500 orbits, February 9, 2010.

• Very good scientific performance

• Cycle-1: Dec. 2007- Nov. 2008 • Cycle-2: Dec. 2008- Nov. 2009 • Cycle-3: Dec. 2009- Nov. 2010 • Approved funding : end of 2010, mission extension to 2012 requested

The data becomes public after 1 year AGILE’s scientific strengths

• Combination of co-aligned gamma-ray (50 MeV – 5 GeV) and hard X-ray (20-60 keV) imagers

• Optimal sensitivity near 100 MeV

• Millisecond data acquisition

• Cosmic and Terrestrial phenomena studied by the same Mission The AGILE gamma-ray sky (E > 100 MeV) 2 year exposure: July 2007 – June 2009 AGILE-2: 2-month intensity map (E > 100 MeV) (Nov.- Dec. 2009) preliminary Main scientific discoveries

• The brightest gamma-ray blazars: (3C 454.3, PKS 1510-089, TX 0716+714, Mrk 421,…) • Several (~10) new Pulsars and PWNs • Discovery of gamma-ray transients in the Galaxy • Discovery of gamma-ray emission from Cygnus X-3 • Microquasar studies, Gal. compact objects • SNRs and origin of cosmic rays, evidence for proton acceleration • Gamma-Ray Bursts, delayed emission, short GRBs • Detection of the very large energy events in the atmosphere from Terrestrial Gamma-Ray Flashes AGILE and Terrestrial Gamma-Ray Flashes (TGFs)

Normal lightnings involve a potential difference ΔV ~ 500 kiloVolts Terrestrial Gamma-Ray Flashes (TGF) involve ΔV > 100 Mega Volts AGILE: what makes MCAL unique for TGFs:

• Only instrument in equatorial orbit – TGF on the equator – low-background • Only instrument with sub-msec trigger capability • Instrument with the best capability at E > 30- 40 MeV Example of a TGF detected by AGILE AGILE - Conclusions

• AGILE is a very successful Mission of the Italian Space Agency

• It is operating in synergy with other international space missions, in particular the NASA gamma-ray mission Fermi

• Many scientific discoveries in the Galaxy and in deep space

• Also working as an observatory for Terrestrial high- energy phenomena !

• Very cost effective Swift

Launched on November 20, 2004

Swift is a NASA-MIDEX mission with participation of Italy and UK. Mission extension approved until 2012. Further extension to 2014 proposed Italian contribution: •Malindi Ground Station (ASI) •X-ray mirror and calibration (INAF - Brera Astronomical Observatory) •INAF science team •XRT data reduction software and archive (ASI Science Data Center) Multiwavelength Observatory The most distant object known : GRB 090423 discovered by Swift on 23 April 2009 Optical/UV telescope X-ray telescope

Conclusions

• ASI built and operates AGILE (in cooperation with Italian institutions)

• Participates to highly successful bi/multilateral projects (Swift and Fermi, next is NuSTAR with launch foreseen for February 2012) • Provides multi-mission infrastructures (Malindi and ASDC) • Very cost-effective approach.
